Use wrapped keymaster0 device's value of KEYMASTER_SOFTWARE_ONLY SoftKeymasterDevice always sets KEYMASTER_SOFTWARE_ONLY but this isn't true when wrapping a keymaster0 hardware device. This breaks CTS. Note this with how the wrapper is implemented _some_ keys from the wrapped adapter will be software backed and there is no way to tell in keychain where it'll land.
